vec scaling enhancement and improved harmonization with ALTRIOS

• make an enum like:

  pub enum ScalingStyle {
      /// Min -> Max values are all scaled
      ScaleAll,
      /// Values are scaled proportionally so that min stays anchored when setting max or vice versa
      ScaleProportionally,
      /// Values are all scaled by same absolute amount
      Slide
  }
  fn set_min(&mut self, style: ScalingStyle) -> anyhow::Result<()> { ...}
  

• make a new crate that both ALTRIOS and FASTSim-3 have as a dependency so that all the commonality can be in one place
• implement TrackedState and TrackedStateWithMemory in the above new crate so that state mutations, if expected, are guarnteed

Start by locating the existing vec scaling and state-tracking implementations in FASTSim-3, then compare the shared behavior needed by ALTRIOS. Define the shared crate boundary and the ScalingStyle, TrackedState, and TrackedStateWithMemory requirements before implementation. Done means both projects can depend on the crate and state mutations are guaranteed as expected.
